1 Claim. 1

This invention relates to a swivel hanger for suspending a punching bag from a rebound board.

An object of the present invention is to provide a hanger of the above kind which will securely retain the punching bag when being used, but which will allow quick and easy removal of the bag for storage of the same or for replenishment of air therein, when desired.

Another object is to provide a hanger of the above kind which is simple and durable in construction and which provides for free universal movement of the bag relative to the rebound board.

The exact nature of the present invention, as Well as other objects and features thereof, will become apparent from the following description when considered in connection with the accompanying drawings, in which:

Figure l is a fragmentary view partly in central vertical section and partly in elevation, showinga swivel hanger constructed in accordance with the present invention.

Figure 2 is a fragmentary sectional view showing the ball stem of Figure l, with the locking sleeve in raised position for allowing disconnection of the lower stem section from the upper stem section.

Figure 3 is a fragmentary horizontal section taken substantially on line 3--3 of Figure 1, and drawn on a reduced scale.

Figure 4 is a horizontal section taken on line 4-4 of Figure 3.

Referring in detail to the drawing, the present hanger comprises a cylindrical socket member 5 which is fitted in a central opening 6 of a rebound board 1 and which has an annular external flange 8 on its lower end countersunk at 9 in the lower face of and secured to the board 1 by nutted bolts H] passing through apertures in said flange and said board. A ball member II is loosely disposed in the socket member 5 and is held therein for free universal movemen u relative thereto by means of a series of bearing balls l2 disposed in an internal annular groove !3 provided in the lower portion of the socket member 5 and engaging the ball member ll below its equator. Upward movement of the ball member I! is prevented by means of a plurality of uniforml spaced pins l4 held in transverse openings of the socket member 5 by means of set screws I5 and having projecting inner ends engaging the ball member I l above its equator.

Depending from the ball member ll is a stem having a reduced upper end portion [6 suitably fixed to said ball member and composed of interlocked male and female sections I! and I8 coupled for quick connection with or disconnection from each other b lateral sliding movement of the lower one of said sections relative to the upper one thereof. As shown, the upper section has a T-head [9 on its lower end slidably fitted in an open-ended transverse T-shaped groove 26 provided in the upper end of the lower section. The sections are releasably held in aligned coupled relation by means of a locking sleeve 2| slidable downwardly over the coupled ends of the sections or upwardly from the same. The upper section has a radially movable spring-pressed ball detent 22 engageable in the respective ones of internal annular grooves 23 and 24 provided in and near opposite ends of the sleeve, to respectively hold said sleeve in lowered locking position as shown in Figure 1 or in raised released position as in Figure 2. When the sleeve 2| is lowered as shown in Figure 1, it will be apparent that it effectively prevents disconnection of the stem sections, and when said sleeve is raised as shown in Figure 2, disconnection of the stem sections is freely permitted. This coupling provides for easy and expeditious mounting of the punching bag for use or removal thereof for storage or replenishment of air therein as will be apparent. Also, when the bag is suspended as shown in Figure 1, the sleeve 2| effectively prevents accidental disconnection of the bag from the rebound board.

The lower end of stem section [8 is longitudinally bifurcated to provide spaced arms 25 having aligned transverse apertures for reception of a nutted bolt 25. The punching bag B is provided at the top with the usual suspension loop 2! in the form of a strap having its ends attached to the tip of the bag. This suspension loop has a spacer block 28 disposed therein, and the loop and the spacerblock have transverse openings through which the bolt 26 extends to attach the bag to the stem. Of course, by threading the nut off of bolt 26 and removing said bolt, the bag B may be completely detached from the stem. Ordinarily, however, quick dismounting of the bag will be eifected by disconnection of the lower stem section from the upper stem section, the lower stem section remaining connected with the bag.

From the foregoing description, it will be seen that the device is comparatively simple, compact and durable in construction, that it provides a most desirable means for suspending the punching bag from the rebound board, and that it affords a secure connection of the bag with the 3 rebound board which permits quick intentional mounting or dismounting of the bag. Minor changes in details of construction are contemplated, such as fairly fall within the spirit and scope of the invention as claimed.

Having described the invention, claimed as new is:

In a swivel hanger for punching bags, a rigid stem, means to connect the upper end of said stem to a rebound board for universal movement relative thereto, the lower end of said stem being longitudinally bifurcated to provide spaced arms having aligned transverse apertures, a punching bag provided at the top with a suspension loop having aligned transverse apertures, a spacer block disposed in said loop and having a transverse opening, said loop and said spacer block what is 4 being disposed between said arms, and a nutted bolt passing through the apertures of said arms and said loop and the opening of the spacer block to attach the bag to the stem.
